HOSE-COUPLING.

Application filed March 13, 1919.

10 all ifi/mm t may concern Be it lmown that I, liosnrH P. LAvIGNn, acitizen of the United States of America, residing at Detroit, inthecounty of llayne and State of ill/fichigan, have `intenti-fl certain newand useful Improvements in Hose- Couplings, of which the following is aspecification, reference being had therein to th accompanying drawings..

rlhis invention relates to a hose coupling and has special reference toa coupling that may be advantageously used for establishingcommunication between the radiator and the water jacket of an internalcombustion engine, such structures forming part of an auto mobile orself propelled vehicle.

The primary `object of my invention is to provide positive and reliablemeans, in a manner as hereinafter set forth, for connecting a flexibleconduit, as a hose, to a rigid conduit as a metallic pipe or tube, so asto establish a non-lea'lrable Iconnection between the flexible and rigidconduits.

Another object of my invention is to provide novel sheet metalinterlocking` coupling .members, one of which can beY easily and quicklymounted on the end of a section of hose and firmly held thereby, whilethe other member is adapted for contracting the first mentioned member,so that the end of the hose will be frictionally clamped on the end of apipe.

A further object of my invention is to provide a hose coupling whereinthe parts are constructed with a view of reducing the cost ofmanufacture and at the same time retain those features by whichdurability, safety and ease of assembling are secured. idith such endsin view my invention resides in the novel construction, combination andarrangement of parts to be hereinafter specilically described and thenclaimed.

Reference will now be had to the drawing, wherein- Figure 1 is alongitudinal sectional view of a hose coupling in accordance with myinvention;

Fig. 2 is a side elevation of a detachable member;

Fig. 3 is a similar view of a fixed member relatively to a section ofhose; and

Fig. l is a cross sectional view of a portion of the same illustratingthe manner in which the fixed member is held against ro tationon the endof a hose.

In the drawing, the reference immoral l denotes a lined member lthat isformed of sheet metal and said member has an inner pressed screwthreadedportion 2 andan outer tapering .nose portion 3. The nose portion of themember 3 has a plurality of longitudinal slots or slits il, so that thenose portion 3 may be contracted about and on the end ofa section ofhose rilo 'limit the fitting `on movement of the member l on the hose 5,the nose portion 3 of said member has inturned edges or Aflanges 6, andto prevent rotation of said member `on the hose 5, the nose portion 3 ofsaid member, between the slots or slits il, has longitudinal depressedportions providing inwardly prejecting ribs 7. rThese ribs are adaptefflto engage in the walls of the :hose 5 yand prevent circumferentialcreeping of the member l on the hose 5, particularly when a detachablemember is placed in engagement therewith.

The reference numeral 8 denotes the end of a rigid conduit, as a pipe onwhich the hose 5 is to be mounted and held to communicat therewith, but'before placing the end of the hose on the pipe 8, a detachable member 9is slipped on to the end of the pipe 8. This detachable member issomewhat in the form of a cap and has a threaded portion l0 and atapering or nose portion 11. rlhat portion of the detachable memberbetween the ends thereof is lrnurled or roughened so as to be readilyrotated by hand and has a plurality of openings or sockets 12 so that aSpanner wrench or suit- Vthe detachablemember on the fixed member.

The tapering or nose portion ll of the detachable member has an inturnedannular flange 13 and this flange will maintain the inner end of thedetachable member in spaced relation to the pipe 8, so that saiddetachable member can be easily shifted on to the fined member andscrewed thereon. ils the detachable member is screwed upon the fixedmember, the flared inner end portion let of the nose 'l1 engages thehose 8 of the fixed member, and contracts the same to such an extentthat the hose 5 is frictionally crowded about the pipe 8 and the hosewill be so crowded that the rubber or material of the hose will beclamped about the ribs 7 thereby positively holding the fixed mem berhaving the iiared portion 14 thereof at ya greater `angle than theangularity of the ,can be pressed and stamped from sheet metal, nishedto be non-corrodible, and quickly assembled for attaching a flexibleconduit to a rigid conduit when the former can be fitted over thelatter.

@ne embodiment of my invention has been illustrated, but it is to beunderstood that the structural elements are susceptible to suchvariations and modifications as fall within the scope of the appendedclaims.

What I claim is l. The combination with a fiexible conduit adapted tohave a rigid conduit extend therein, of a sheet metal member fixed onthe end of said flexible conduit, and provided with a contractible noseportion, and a sheet metal detachable member adapted to be mounted onsaid fixed member and having a flared portion adapted tocontact with andcontract the nose portion of said fixed member.

2. The combination with a hose and a pipe extending therein, of a fixedmember on the end of said hose provided with a contractible noseportion, and a detachable member adapted to be screwed on to said fixedmember and having a portion to en- Y gage the nose portion of said fixedmember fixed member and adapted for contracting the nose portion thereofso as to clamp said hose on said pipe, and inwardly projecting ribscarried by the nose portion of said fixed member adapted topreventrotation of said fixed member relatively to said hose.

4. The combination with a hose and a pipe extending therein, of a sheetmetal member fixed'on the end of said hose and having a threaded portionand a slotted nose portion, the nose portion of said fixed member beingprovided with inwardly projecting ribs adapted to engage in the hose andprevent rotation of said fixed member relative thereto, and a detachablemember adapted to be screwed on said fixed member, said detachablemember having a nose and iiared portions adapted for engagement with thenose portion of said fixed member so as to contract said nose portionabout the end of the hose and cause said hose to frictionally clamp saidpipe.

In witness whereof I affix my signature in the presence of twowitnesses.
